Normally found in standard inertial reference systems, gyro-compassing enables the unit to establish precise heading within moments, without the use of a magnetic flux valve or magnetometer.

通常放置在标准惯性参考系统中，陀螺仪能够使设备在瞬间建立精确的航向，而不使用磁通阀或者磁力计。

To be more precise, the array reference cannot be changed to point to a different Array, but the array itself can be modified, as shown in the following scala session.

更准确的说，这个引用array 不能被修改指向另外一个Array （数组），但是这个数组本身可以被修改，正如下面的scala 会话中演示的。
